These mandatory inspections catch problems before they become dangerous. Non-compliance can ground an aircraft or result in enforcement action.\n\n**Key point:** This is **not optional** — \"Airworthiness Directives\" are legally binding safety orders. You cannot legally fly the aircraft without complying."},"flash_summary":{"complexity_score":3,"scope_assessment":{"changed":false,"description":"The supplied text is labelled \"Amdt 1\" but contains no comparison to the prior (original) AD text.
